Clear cell meningioma (CCM) has been identified and included in the World Health Organization classification of CNS tumors recently. CCMs are histologically characterized by sheets of polygonal cells with clear cytoplasm, which is the expression of high glycogen concentration. Compared with other variants of meningiomas, CCMs occur in younger patients and usually are located in the spinal canal and posterior fossa, the last ones mainly in the cerebellopontine angle. Some reports suggest that CCMs have high recurrence rate and potentially aggressive behavior. Poor outcome has been shown in intracranial and spinal tumor location, but indicators that predict outcome have not been established. The authors present two cases of intracranial CCMs, with excellent outcome in patients harboring tumor location (restricted to the fourth ventricle) and some clinical particular features (young age, gender, obesity, and moderate impairment of intellectual capacity). To the best of our knowledge, these are the two first reported cases of clear cell meningioma located primarily in the fourth ventricle.

The aim of this study was to examine the use of risperidone in routine clinical care for very aggressive young children. This is a retrospective medical chart review of patients age less than 6 years 11 months who were treated with risperidone for 1 to 10 months during the 1-year study period. Treatment response, side effects, and Clinical Global Impression (CGI) scores were identified. One hundred and five such young children were identified; 8 had been treated with risperidone (6 boys, 2 girls: mean age 4.9 +/- 0.8 years). Risperidone was used in combination with other psychotropic medications in 7 of the 8 children. The mean daily dose of risperidone was 1.25 +/- 0.27 mg. Seventy-five percent of the children were on concomitant lithium, valproate, or carbamazepine; 63% were on stimulants or alpha adrenergics. This was a highly comorbid group, with 7 children presenting with attention deficit hyperactivity disorder and 5 children with bipolar disorder not otherwise specified. The average baseline CGI severity was 5.5 (SD = 0.5), and at last visit it was 3.5 (SD = 0.5), p < 0.0001. Mean CGI improvement score was 1.9 (SD = 0.6). Adverse effects included significant weight gain (mean 5.5 +/- 4.9 kg, p < 0.05) in 6 patients. One child had hyperprolactinemia. Given the potential development of atherosclerosis in obesity and endocrine response in hyperprolactinemia, risperidone should be reserved for those children with severe aggressive behavior who failed multiple trials with other agents. Further controlled trials are needed.

The incidence of diabetes has reached epidemic proportions across the world. In patients with diabetes, there is a two to four times increased risk of developing coronary artery disease (CAD). Diabetes seems to eliminate the protective benefits of hormones in women against CAD. Patients with type II diabetes also have hypertension, dyslipidemia, obesity, endothelial dysfunction and prothrombotic factors, called 'the metabolic syndrome'. Not only the incidence of CAD is higher in diabetes, the mortality of the diabetic patients after a cardiac event is significantly increased as compared to non-diabetics, including sudden death. Although in the past 35 years there has been a decline in the rate of death due to CAD in the general population, this has not been seen among patients with diabetes. Primary prevention can play an important role in decreasing the incidence of CAD in diabetic patients. Aggressive treatment of hyperlipidemia and hypertension is essential. Recent knowledge about the protective effects of aspirin, statins, angiotension converting enzyme inhibitors, and glitazones in the diabetic patients, if used appropriately will go a long way in primary and secondary prevention of CAD in patients with diabetes.

The direct correlation between glucose levels and cardiovascular disease in individuals with type 2 diabetes can now be applied to individuals that share an abnormal metabolic milieu similar to that found in central obesity, the metabolic syndrome, and type 2 diabetes. Premature macrovascular complications with a very high morbidity and mortality rate can be found in these nondiabetic populations. The typical phenotype has visceral or central obesity, excess of free fatty acids, insulin resistance, increased insulin secretion, and hypertension. A more complex metabolic-cardiovascular syndrome develops that includes dyslipidemia, abnormal production of cytokines, chronic inflammatory state, and abnormal coagulation. The interplay of all these cardiovascular risk factors is responsible for the accelerated atherosclerotic process. The different terminologies used for populations sharing this common ground for premature cardiovascular disease now generally accepted as the metabolic syndrome, are also discussed. Aggressive insulin treatment during acute illness in individuals with the abnormal metabolic milieu is beneficial. Insulin treatment is changing from using insulin as a hormone to treat only severe hyperglycemia, to a new paradigm using insulin in high doses as a drug. Aggressive insulin regimens should be used to treat only minimal elevations of blood glucose or to prevent hyperglycemia. The newly observed properties of insulin are reviewed which include suppression of inflammatory cytokines and adhesion molecules, improved hemostasis, and other cardiac beneficial effects. The concomitant administration of intravenous glucose and insulin permits the administration of higher insulin doses that can result in improved outcome due to its nonglycemic-related benefits. The use of aggressive insulin therapy requires both better and more cost-effective algorithms to successfully treat this high-risk population during acute illness.

Polycystic ovary syndrome (PCOS) is a common endocrine disorder characterized by chronic anovulation and hyperandrogenism. PCOS is one of the leading causes of infertility and manifests with hirsutism, acne, and obesity. To investigate its impact on health-related quality of life and sexuality, 50 women with PCOS and 50 controls were evaluated with standardized questionnaires (36-item short-form health survey, symptom checklist revised, and life satisfaction questionnaire). The impact of hirsutism, obesity, and infertility was assessed using five-point rating scales, and sexual satisfaction was analyzed with visual analog scales. Patients showed greater psychological disturbances on the symptom checklist revised dimensions, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, aggression, and psychoticism, along with a lower degree of life satisfaction in the life satisfaction questionnaire scales health, self, and sex. Health-related quality of life measured with the 36-item short-form health survey revealed significantly decreased scores for physical role function, bodily pain, vitality, social function, emotional role function, and mental health in patients with PCOS. Although patients had the same partner status and frequency of sexual intercourse, they were significantly less satisfied with their sex life and found themselves less attractive. Most of the differences were not affected by correction for body weight. In conclusion, PCOS causes a major reduction in the quality of life and severely limits sexual satisfaction.

The visible burrow system (VBS) is an ethologically relevant model of social stress, which has been used to study the aggression of male rats in a social context. Previous studies using the VBS have established physiological, endocrine, and neurochemical characteristics associated with chronic social stress in dominant and subordinate animals. A critical criterion in establishing an animal model for research is the replication of findings and the independent validation of the model. Here, we independently confirm previously reported findings and include novel control groups that are important in dissociating the effects of chronic social stress from those resulting from group-housing the male rats in an "enriched environment". Furthermore, we show that whereas the VBS model is useful for males, it is not effective for studies of females because they do not form dominance hierarchies when housed in groups. We also extend the use of the VBS model to examine the etiology of stress-induced anorexia and obesity, finding that weight loss in subordinate rats is attributable to decreased adipose and lean tissue, whereas in dominant rats, it is associated only with adipose tissue loss. Consistent with this, the adiposity hormones leptin and insulin are decreased in subordinates and, to a lesser extent, in dominants, compared with the controls. In summary, the VBS model of chronic social stress is an ethologically relevant animal model and provides a valuable tool for studies of stress-related conditions and pathologies.

Meetings with a group of 150 teenagers from high school, aged 15-18, were held in the Literary Cafe in Bytom. The problems that were discussed included threats of contemporary world such as: alcoholism, smoking, excessive participation in watching TV, video and Internet. During the meeting drawings, graphics arts and poetry enabled informal entering into conversation with young people and encouraged them to express their opinions. At the next meeting, which took place in High School, a survey was carried out in a group of 33 teenagers. The results of the survey showed that young people assign 6 hours 30 min. on average for rest at night, 3 hours 20 min. on average for watching TV, 2 hours 45 min. for computer, 2 hours 30 min for Internet, 1 hour 30 min for video. 12 out of 27 teenagers are mentally and physically tired after school, 15 teenagers have a rest after school, 18 teenagers fell ill during the school year and answered that they are nervous. 6 answered that they are sometimes nervous. 17 young people like alcohol and tried have it and 6 were drunk up. 14 teenagers like commercials on TV and 19 do not like them 27 children do not belong to any organisations. 12 teenagers have smoked cigarettes and 9 rarely have smoked cigarettes. 1 teenager has taken drugs. American Academy of Pediatrics, Committee on Public Education describes the possible negative health effects of television viewing on children and adolescents, such as violent or aggressive behavior, substance use, sexual activity, obesity, poor body image, and decreased school performance. In addition to the television ratings system and the v-chip (electronic device to block programming), media education is an effective approach to mitigate these potential problems. The European Society of Social Paediatrics (ESSOP) and American Academy of Pediatrics (AAP) offers a list of recommendations on this issue for pediatricians and for parents, the federal government, and entertainment industry.

Goal blood pressure (BP) was defined by the Sixth Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC-VI) and the World Health Organization-International Society of Hypertension (WHO/ISH) as <140 mm Hg systolic and <90 mm Hg diastolic for the general and <130 mm Hg systolic and <85 mm Hg diastolic for special high-risk populations. However, there are few reports that address BP control among special subgroups of hypertensives by reference to targeted BP. We therefore conducted a study to evaluate BP control of 4049 hypertensives in 47 hospital-based hypertension units in Spain. Overall, 42% of patients achieved goal BP (<140 mm Hg systolic and <90 mm Hg diastolic). Only 13% of diabetic patients and 17% of those with renal disease achieved the BP goal (<130 mm Hg systolic and <85 mm Hg diastolic), and only 10% and 12%, respectively, achieved the even more rigorous goal (<130 mm Hg systolic and <80 mm Hg diastolic). Likewise, only 18% of patients in JNC-VI risk group C and 17% of WHO/ISH high-risk patients attained a goal BP <130 mm Hg systolic and <85 mm Hg diastolic. BP control (<125 mm Hg systolic and <75 mm Hg diastolic) was extremely low (2%) in patients with proteinuria >1 g/d. Poorer BP control was observed among patients at high risk, with diabetes, renal disease, or obesity, than in lower-risk groups. BP control was lower for systolic than for diastolic BP. In >50% of uncontrolled patients, no measures were taken by doctors to optimize pharmacologic treatment, and approximately one-third of patients were still using drug monotherapy. Control of BP, particularly of systolic BP, is still far from optimal in hospital-based hypertension units. Patients at high risk, with diabetes or proteinuria, warrant focused attention. Moreover, a more aggressive behavior of doctors treating uncontrolled hypertension is needed.

Advances in the management of the mother with diabetes have reduced the rate of morbidity and mortality for her infant. Aggressive control of maternal glycemic status is warranted, because most morbidities are epidemiologically and pathophysiologically closely linked to fetal hyperglycemia and hyperinsulinemia. The burgeoning public health problem of overweight and obesity in children will likely result in an increased incidence of metabolic syndrome X, characterized by insulin resistance and type II diabetes in adulthood. An early manifestation of this may be glucose intolerance during pregnancy in overweight women without diabetes. Clinicians must continue to have a high degree of suspicion for the diagnosis of diabetes during gestation and screen offspring of women with gestational diabetes for neonatal sequelae.

Calciphylaxis is a confusing disease process that affects people with end-stage renal disease. The prognosis of this increasingly common condition is poor and mortality rates range from 60% to 80% related to wound infection, sepsis, and organ failure. Its presenting sign is skin necrosis related to calcification of the arteriole microvasculature. The disease is painful and debilitating, particularly due to the necrotic wounds. Aggressive wound care to prevent infection is vital when eschar does not protect the wound and drainage is present, but debridement is contraindicated for wounds covered with dry, noninfected eschars. The decision to debride is based on the patient's total clinical picture. Patients with calciphylaxis have poor healing potential due to ischemia and comorbidity factors such as diabetes mellitus, peripheral vascular disease, and obesity. The goal of care is prevention of infection and pain management. Some of the sensitizers and challengers responsible for the chemical imbalance leading to the arteriole calcification, as well as risk factors and clinical manifestations of calciphylaxis, are reviewed. A discussion of treatment focuses on wound care of stable necrotic ulcers and a case report illustrating the progression of calciphylaxis is presented.
